I understand that I can re-use asphalt and concrete paving on the site for this credit, but does this also apply to the 6" type "A" crushed stone aggregate base below these paving types. We salvaged concrete and asphalt paving along with the crushed rock base when we started the project. We then ground this material and placed it back as compacted base material (8" thickness) under a much thinner asphalt paving.
